I saw this last night. http://www.wishtv.com/news/local/6-chickens-die-in-shed-fire Very tragic. I'm actually using one myself. I'm going to make sure it's on cinder blocks and not sitting direct on the litter. (I only have it in the coop when it's so cold during the day and never at night). This article made me realize that I need to be more careful as well.
